Hard work really does pay off.

Lady Gaga stunned even her haters (well, almost all of them, but we'll get to that later) with her "The Sound of Music" tribute on Sunday night's Oscars. While better known for pop songs like "Poker Face" and wearing crazy outrageous costumes, she sounded sounding amazing performing a medley of the classic tunes including "My Favorite Things," "Edelweiss" and "Climb Ev'ry Mountain" in a gorgeous gown fit for a princess.

But the flawless vocals weren't exactly effortless -- Oscars executive producers Neil Meron and Craig Zadan revealed to ET that the 28-year-old singer actually practiced every day for six months for the 50th anniversary tribute.

"She worked half a year with a vocal coach every day for half a year to do that," Zadan told ET.

Meron also revealed just how seriously the "Applause" singer took the performance.

"She said that if she pulls it off, it's going to change the focus of her career and she pulled it off," he said.

"I'm just very excited to be here and I really put my heart into this performance," Gaga herself told ET on the Oscars red carpet. "It's a tribute performance for a remarkable film that changed the history of cinema forever, and I'm just very honored to be doing it."

But though Gaga's been getting rave reviews for her surprising performance, one person clearly not impressed is "Scandal" showrunner Shonda Rhimes.

Rhimes tweeted about Gaga's performance on Sunday, and let's just say the review is far from glowing.

That was not okay. I mean, Idina is there. She is right there. RIGHT THERE. And oh dear God, Julie had to hear that. #Oscars2015
